The other end of the tongue plate 20 is provided with a welding area 24, and a position of the welding area 24 corresponds to the hollow stage 15. One of the sides of the tongue plate 20 is a front surface 21, and the front surface 21 is arranged correspondingly to the hollow stage 15. That is, the front surface 21 of the tongue plate 20 faces the hollow stage 15. In the present embodiment, an edge of the tongue plate 20 is clamped between the upper shell 13 and the lower shell 14. Specifically, a plurality of support portions 22 are formed on both sides of the tongue plate 20, and the upper shell 13 and the lower shell 14 are convexly provided with a plurality of bumps 133 and 142. The supporting portions 22 of the tongue plate 20 are respectively attached to the bumps 142 of the lower shell 14 for support, and press the tongue plate 20 through the bumps 133 of the upper shell 13 to fix it.

Each cable 30 is wrapped in at least one wire harness A. Each cable 30 passes through the butting end 12 and penetrates into the housing 10 respectively, and is inserted into the housing 10 that is columnar. At least a part of the cables 30 is stacked on a surface of the tongue plate 20 corresponding to a position of the hollow stage 15. The hollow stage 15 provides extra space inside the housing 10 and allows more cable 30 to be connected to the tongue plate 20. In the present embodiment, at least a part of the cables 30 are respectively stacked on the front surface 21 of the tongue plate 20 and accommodated between the front surface 21 of the tongue plate 20 and the hollow stage 15. According to an allocation of space in housing 10, any remaining cable 30 may be connected to the other side of tongue plate 20. The present disclosure is not limited thereto. All the cables 30 may also be connected to the front surface 21 of the tongue plate 20.

In the present embodiment, each cable 30 connected to the front surface 21 of the tongue plate 20 constitutes a plurality of line rows 31, and the end of each cable 30 in the plurality of line rows 31 is respectively connected to the front surface 21. The plurality of line rows 31 are stacked on top of each other to allow a connection between the line rows 31 and the front surface 21 to be parallel to the front surface 21, so that a space of the front surface 21 of the tongue plate 20 may be effectively used. In the present embodiment, a number of the line rows 31 on the front surface 21 of the tongue plate 20 is two. The present disclosure is not limited thereto. For example, a number of line rows 31 on the front surface 21 of the tongue plate 20 may also be three, four, or five . . . etc., depending on a design requirement. Please refer to FIG. 6 and FIG. 7 , which show another embodiment of the present disclosure. A main difference is that the number of line rows 31 on the front surface 21 of the tongue plate 20 is three.

Each heat sink 40 is integrally formed on (or in one-piece form with) the housing 10. The heat sinks 40 are arranged on the top surface 131 of the upper shell 13 in parallel and spaced apart and located at the butting end 12. That is, each heat sink 40 is arranged on a side of the hollow stage 15 away from the docking end 11. The plurality of heat sinks 40 are arranged parallel to each other, and the plurality of heat sinks 40 is surrounded and formed with a plurality of flow channels 41 extending parallel to a longitudinal direction of the housing 10. Thereby, a heat energy generated by the tongue plate 20 and each cable 30 during operation may be conducted upwards into the hollow stage 15, and the heat energy is taken away by the natural air convection through the two through openings 151 of the hollow stage 15. When the natural air convection flows through the flow channels 41, the heat sink 40 contacts the natural air convection to achieve the effect of cooling. The plurality of heat sinks 40 includes a plurality of rows with a plurality of protrusion 42 arranged in parallel. A plurality of recesses 43 are formed between each of the protrusions 42, and the plurality of protrusions 42 and the plurality of recesses 43 are continuously and alternately extended along a direction of a connection with the docking end 11 and the butting end 12. A height of the plurality of protrusions 42 is equal to or lower than a height of the two side walls 16, so that each of the protrusions 42 maintains a structure of the flow channel 41. At the same time, air flow is guided from the plurality of recesses 43 to different flow channels 41, so that each heat sink 40 uniforms thermal energy and improves heat dissipation efficiency. As shown in FIG. 8 , each heat sink 40 may also reserve a root part 44 at a junction with the top surface, and the plurality of protrusions 42 and the plurality of recesses 43 are integrally formed on (or in one-piece form with) an upper edge of the root part 44.

Further, the cable connector of the present disclosure further includes an unlocking assembly 50 and a plurality of return springs 60. The unlocking assembly 50 may be a plastic part, which mainly includes a handle 51 and a locking member 52 connected to the handle 51. The handle 51 is of an inverted U-shape, and the locking member 52 includes at least one elastic arm 521. In the present embodiment, two elastic arms 521 with the same structure and functions are preferably configured, and the two elastic arms 521 are connected by a connecting arm 522. The two elastic arm 521 are respectively connected to the two ends of the handle 51 and used to release the cable connector. The housing 10 is provided with an actuating portion 144 on both sides of the butting end 12 corresponding to each elastic arm 521. In the present embodiment, each actuating portion 144 is preferably a slope surface. The present disclosure is not limited thereto. The actuating portion 144 may also be a protruding structure that may interfere with a movement stroke of the elastic arm 521 and push the elastic arm 521. As a result, when the handle 51 is pulled backward, the locking member 52 may be driven to move backward, and each elastic arm 521 is pushed against each actuating portion 144 so that each elastic arm 521 moves outward along a lateral direction of the housing 10. When the cable connector structure of the present disclosure is mated to the mating docking connector, the mating docking connector is locked by hooking into the cable connector structure with a structure such as a locking hook. Preferably, a hooking position corresponds to the elastic arm 521, so the mating docking connector is locked by the elastic arm 521. By moving the elastic arm 521 outwards, the mating docking connector is retracted and the cable connector structure is released.

The lower shell 14 is provided with a slot 143 on both sides of the butting end 12 corresponding to each elastic arms 521, and each slot 143 is provided with the return spring 60. Each elastic arms 521 includes a lug 5211 protruding toward the lower shell 14 corresponding to the return spring 60. The locking member 52 is socketed on the butting end 12 of the lower shell 14, and the handle 51 is located outside the butting end 12 and straddles the wire harness A. Specifically, the connecting arm 522 is located below the lower shell 14, and the two elastic arms 521 are attached to the left and right sides of the lower shell 14 and cover the slot 143. The lug 5211 of each elastic arms 521 is located in the slot 143, and the return spring 60 is clamped between the lug 5211 and the slot 143 by an elastic force of the return spring 60. When the handle 51 is pulled backwards, the locking member 52 is driven to move backwards. At the same time, the corresponding return spring 60 is pushed by each lug 5211 for compression. When the handle 51 is released, the unlocking assembly 50 is restored to its position through the elastic force of the return spring 60. In the present embodiment, the elastic arms 521, the return spring 60 and the slots 143 are arranged in pair and in mirrored manner. However, the present disclosure does not limit thereof.
